The royal commission into child sexual abuse has heard former national swimming coach Scott Volkers was exempt from holding a blue card in Queensland, despite the fact his application was rejected.

He applied for the blue card - which is needed for working with children - along with about 60 other employees from the Queensland Academy of Sport in mid-2008.

The royal commission has heard Mr Volkers' application was the only one to be issued with a negative notice and his application for a blue card was rejected.

The commission is currently examining how sports bodies and top prosecutors handled allegations of sexual assault made against Mr Volkers by three former students.

Julie Gilbert, Kylie Rogers and Simone Boyce each allege they were abused between the ages of 12 and 14 while swimming in Mr Volkers' training squad in the 1980s and 1990s.

Mr Volkers was committed to stand trial but charges against him were dropped by the Queensland Director of Public Prosecutions in 2002.

The director of Queensland's blue card system, Michelle Miller, has told the inquiry the recommendation to reject Mr Volkers' application was handed down before it was decided he was exempt from the requirement to hold a blue card because he was a government employee.

On Wednesday, Swimming Queensland chief executive Kevin Hasemann agreed to review Mr Volkers' status as a life member of the organisation and a Hall of Famer.

Mr Hasemann admitted to the commission he did not investigate the allegations against Mr Volkers before employing him.
